HOL'DBACK FOR HAM ES.

SPECIFICATION forming part of Letters Patent No. 243,891, dated July 5,1881,

Application filed May 31, 1881. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM B. HAYIJEN,

a citizen of the United States, residing at Golnmbus, in the county ofFranklin, State of Ohio, have invented new and useful Improvements inHoldbacks for Hames, of which the following is a specification. I

This invention relates to certain improvements in holdback attachmentsfor harnesshames, the object being to provide an efficient means ofre-enforcing and strengthening the hames, and thus prevent weakening ofthe same at the point of attachment of the usual draw-clip, staple, andbreast-ring; also, to prevent said ringfrom twisting or turning in itsplace, and to produce a more ornamental hame than has been heretoforeused.

Holdback attachments have been applied to hames by means of a platesecured by bolts, or by the prongs of an ordinary staple. This plate hasalso been secured by the breast-ring stud. These methods obviated manyof the difficulties previously experienced and relieved the hames ofconsiderable strain; but they were still liable to be unduly weakened byreason of the number of apertures that were required to be made throughthem for the passage of the attaching bolts and staples.

My present invention is designed to obviate the objectionable featuresabove referred to; and to this end it consists, first, in a menforceplate of such shape as to adapt it to conform closely to the hame, towhich it is attached by a single shank formed in one piece with the saidplate, which is further provided with an eye or clip, also forming apart thereof, and with a suitable perforated boss having a transversecountersunk recess for the passage of the breast-ring stud; second, inthe combination, with the re enforce plate and its perforatedcountersunk boss, attached to the hame by a single shank, of thebreast-ring and its stud, the latter passing through its aperture in theplate and through the hame at a right angle to the shank by which theplate is se cured, ashereinafter more fully set forth.

In the drawings which fully illustrate the invention, Figure 1represents a front view of the lower portion of the hame, showing myinvention applied thereto. Fig. 2 is a vertical section of the same onthe line w Fig.

3 is a transverse section on the line y y. Fig. 4 is a view of" there-enforce plate detached, and Fig. 5 is a view of the breast-ring andits stud.

Similar letters of reference indicate corresponding parts in the severalviews.

The letter A indicates a portion of a hame, which may be constructed ofwood or any suitable material in the ordinary manner, and is provided onits outer edge with the usual metal strengthening-strap, B.

The metal re-enforce or attaching plate 0 is constructed with a narrownearly flat portion, having an inner surface which is adapted to restagainst the strap B, and forms the base of an eye or clip, D, composinga part of the plate. At the upper part of this fiat inner surface is ahorizontal shank or pin, E, which also forms a part of the plate, andpasses transverselythrough a suitable aperture in the hame, I

where it is secured by riveting it, as at a, upon a washer, b, as shownin Fig. 1.

Extending downward obliquely from the base of the eye or clip D, theplate 0 has a curved outline and an inner surface, by which it isadapted to conform closely to the curvatures of the hame, against thefront of which it rests. At the lower end of this oblique curved portionof the plate 0 is araised boss, 0, having an aperture, d, and atransverse countersunk recess, 0, through the edge of the same. Theaperture D in the lower end of the plate 0 corresponds in position withan opening made through the hame at a right angle to and below theopening that receives the shank E. Through this opening d, and alsothrough the fhame,is passed the stud or bolt f of the breastring F,which is secured by riveting, as at a, upon a washer, b, as shown inFig. 2. The boss 0 is depressed around the edge of the aperture d insuch a manner as to accommodate the rounded surface of the head or eyeat the end of the bolt or stud f, through which the breast-ring ispassed; and, together with the countersunk recess a, which receives andforms a seat for the breast-ring, serves to preventit from beingdislocated by twisting or turning.

It will be observed that by my invention only two perforations arerequired to be made through the hame, one for the passage of the shankforming a part of the reenforce plate and the other, below and at rightangle to the first, for the passage of the breast-rim g stud. Theconstruction of the re-enforce plate is also such that the openingswhich are thus made through the hame do not need to be countersunk, asis often required, and therefore a great source of weakness is entirelyavoided. The openings through the hame for the passage of theplate-shank and breast-ring stud being at a right angle to each otherand separated by a considerable space, owing to the oblique curvature ofthe re-enforce plate, it is apparent that the hame will possess agreater degree of strength than usual, and'that the strain upon the hameand its attachments will be distributed and equalized by the plate insuch a manner as to preserve the integrity of the parts unimpaired evenwhen subjected to severe strains.

Having thus described my invention, what I claim is-- 1. A re-enforceplate for hames, having a single attaching shank formed in one piecewith the plate, which is further provided with an eye or clip, alsoforming a part thereof, and

with a perforated boss having a transverse countersunk recess for thepassage of the breastring stud at a right angle to the plate-shank, theaperture in the boss being adapted to form a seat for the enlarged headof the breastring stud and the countersunk recess a seat for thebreast-ring, whereby said ring is prevented from turning or twisting,substantially as specified. I

2. The combination, with a re-enforce plate for hames, having a singleattaching-shank and a perforated boss provided with a transversecountersunk recess, of a breast-ring and its stud, adapted to passthrough the hame below and at aright angle to the plate-shank, andseated in the depressed portion of the boss and its countersunk recess,substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
